AWS Infrastructure
AWS Tutorial: AWS Global Infrastructure Deep Dive
Welcome to the AWS Global Infrastructure lesson. To truly master the cloud, you must understand the physical hardware and global network that makes AWS the most robust cloud provider on Earth.
Why Learn About AWS Infrastructure?
The cloud isn't magic; it's physical data centers connected by massive trans-oceanic fiber optic cables. Understanding this global footprint allows you to design highly available, fault-tolerant architectures that can survive entire natural disasters.
Tutorial Overview
In this tutorial, you will learn the hierarchy of the AWS network:
- Global Network: The backbone connecting the world.
- Regions: The macro-level geographical boundaries.
- Availability Zones: The micro-level isolated fault domains.
The Physical Cloud
AWS operates a state-of-the-art, highly available global network. Unlike the public internet, which routes data unpredictably, AWS has its own private, custom-built global network infrastructure connecting its regions using redundant 100GbE fiber networks.
The architecture is strictly hierarchical:
- Regions are large geographical areas (like "Europe" or "US East").
- Inside every Region are multiple Availability Zones (AZs).
- Inside every AZ are one or more physical Data Centers.
